itsme is a mobile-app-based eID used across Belgium and the Netherlands, run by Belgian Mobile ID. There's no card reader and no password: the user confirms everything in the itsme app on their phone. It's used for logging in, confirming transactions and signing documents, and an itsme signature carries the same legal weight as a handwritten one.

In eID Hub, itsme is the provider itsme and supports both authentication and signing. Signing goes through itsme's own qualified electronic signature (QES) flow rather than eID Hub's generic CSC integration.
